UNITE STATES PATENT OFFICE.

WALTER GRUIVIBAGHER, OF NEW YORK, N. Y.

Application filed August 17, 1923/ Serial No. 657,916.

To all whom it may concern:

Be it known that I, WALTER GRUMBAcHER, a citizen of the United States,and a resident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Brushes, of which the followingis a full, clear, and exact specification.

My present invention relates generally to brushes and more particularlyto an arrangement, for holding bristles within a holder.

While as will be observed, I have disclosed my invention herein asapplied to a brush in which the handle member is a quill within one endof which the bristles are received and held because it is in thisspecific association that my invention was first evolved, neverthelessit will be understood that my invention possesses utility in brushesother than of the specific character in connection with which thisinvention is herein disclosed.

Among the more important objects of. my invention is the provision of abrush which while simple in construction and economical in cost isnevertheless efiicient in operation and unobjectionable in use.

For the attainment of these objects and of such other objects as willappear or be pointed out hereinafter, I have illustrated one embodimentof my invention in the drawings wherein:

Figure 1 is a view in side elevation of the brush; and

Figure 2 is a longitudinal section taken on line 22 of Figure 1.

Upon Viewing the figures of the drawing it will be observed that I haveherein illustrated a brush which comprises the bristles 10, and thehandle member 11. This handle member 11 is preferably in the form of aquill within the end 12 of which the bristles are received. Thebristles, as will be observed, are inserted into the end 12 of the quill11 for a substantial distance. For sesuring these bristles in positionin the quill, I employ a wire 14 which is wound about the quill 11 at apoint 13 which is substantially intermediate the ends of that length ofthe bristles which is received within the end 12 of the quill 11.

The wire 1& is preferably wound about the quill more than once, forreasons that will be obvious; for instance in the drawing, I

show the wire as wound thereabout twice. The wire is preferably drawntight about the quill 11 in fact sdtight as to compress and narrow thequill at the point 13 and therefore to correspondingly compress the 5bundle of bristles within the quill 11. The ends 15 of wire arepreferably then twisted as shown in 16 thereby keeping the'wireends fromseparating and the 'wire from loosening. These twisted ends are thenbent paral lel to the longitudinal axis of the quill as shown in thedrawings.

Upon viewing the figures of the drawing it will be observed that Ipreferably turn this end 16 downward, i. e. toward the bristle end ofthe brush and into parallelism therewith and then fforce this end withinthe outlines of the brush as shown at 17 7 all for reasons that I willnow point out.

As is well known a brush of this type is generally cleaned or wiped bymoving a cloth or a similar article into contact with andalong the brushin the general direction of the bristle end. By turning the end 16downward i. e. toward the bristle and the brush, as already described, Itherefore attain one of the important objects of my invention which isthat the ends 15, 15 being bent in the general direction of the movementof the-wiping element will not catch into the wiping material or in anyother way interfere with the movement or use of the wiping action.

Additionally by forcing this end 16 with in the outlines of the brush,the bristles are further compressed thereby. In fact, this end 16 actssomewhat as a wedge increasing in size in the direction of the bristleend and thus serving to hold the bristles against falling out of thebrush.

Having thus described my invention and illustrated its use what I claimas new and desire to secure by Letters Patent is the following:

1. In a device of the character described, a compressible tubular handlemember, bristles positioned therein and a bendable 'member wound tightlyabout said tubular member to compress it so as, to produce aninterengagement between the. handle member and the bristles, the freeends of the bendable member being interengaged and twisted and then bentlongitudinally a an interengagement between .the handle '7 avcompressible tubular handle member,

bristles positioned therein and a bendable member wound tightly aboutsaid tubular member to compress it so as to produce an interengagementbetween the handle member and the bristles, the free ends of thebendable member being interengaged and bentv longitudinally of thehandle member'and in the direction of the bristles.

\ 4. In a device of the character described, a compressible tubularhandle member, bristles positionedw therein and a bendable member woundtightly about said tubular member to compress it so as to produce aninterengagement between the handle .memberfand the bristles, the freeends of i the bendable member being bent longitudinally of the handlemember and in the direction of the bristles, said free ends being forcedinto angular engagement with the handle member so as to cause a wedgingengagement between the bristles and the handle member.

'5. In a device of the character described,

a compressible tubular handle member,

bristles positioned therein and a bendable member wound tightly aboutsaid tubular member to compress it so as to produce an interen agementbetween the handle member and the bristles, the free ends of thebendable member being interen ged and twisted and then bentlongitudmally of the handle member and in the direction of the bristles,said free ends being forced into angular engagement with the handlemember so as to cause a wedging engagement between the bristles and thehandle member.

In testimony whereof, I have hereunto signed my name.

WALTER- GRUMBAUHER.
